IMPROVED JOURNAL-BOX.

,a cross-section through one of the oil-cups,

and Fig. 3 represents a longitudinal central section of the lower half ot the journal-box without the back B.

In the drawings, A represents the lower halt' of the box, from the back ot' which rises the back piece, B, against which the top half of the box C tits when in place, as indicated in the drawings. The cap or upper halt', C, of the box is cast with two oil-cups, t a., the bottoms of which communicate each with a chamber, b. From the lower part ot' each chamber l) pass small holes e to the middle-of the box.

The oil-cups a an d their chambers b are filled with cotton, wool, or some fibrous material, as seen at 0. The center of the lower halt'ot' the box is also cored out and filled with fibrous material, as seen at el, while central inclined grooves, l l, lead into the space tilled with the 'tibrous material d. The lower half, A, of the box is babbitted as seen atf, while the upper half is babbitted, as seen at g.

The operation is as follows: Oil or some proper lubricating substance is turned into the oil-cups a, where it saturates the fibrous material c in said cups and their chambers b. It then gradually passes through the holes e to the shaft orjournal. In case the supply ot oil is sufcient to cause it to run down it is conveyed by the inclined grooves l l to the space D in the part A, where itis taken up by the fibrous material d and brought in contact with the revolving shaft or journal.

The above-described journal-box has been tested upon bearin gs subjected to great strain and wear, and has been found to keep the journal well and constantly lubricated, and that, too, with a very small amount of oil.

Having described my improved journal-box, what I claim as new therein, and desire to secure by Letters Patent, is-

A journal box or hearing composed of a base-piece, A, cored out, as seen at D, and having inclined grooves 1 1, in combination with a cap, G, having oil-cups a a, chambers b I), and holes e, the parts being all constructed andarranged for joint operation as set forth.
